Heterogeneous nucleation, nucleation with the nucleus at a surface, is much more common than homogeneous nucleation.
12.
So we will outline the CNT calculation for the homogeneous nucleation barrier \ Delta G ^ *.
13.
Normally, when temperatures reach minus 40 degrees, water vapor spontaneously condenses into ice, a process called homogeneous nucleation.
14.
In these cases homogeneous nucleation occurs : particles are formed without the presence or need for surfactant micelles.
15.
Homogeneous nucleation describes when the nuclei are formed spontaneously in solution while heterogeneous nucleation describes when the nuclei are grown on other species.
16.
Heterogeneous nucleation is typically much faster than homogeneous nucleation because the nucleation barrier & Delta; G * is much lower at a surface.
17.
Particle formation in the former is a mixture of micellar and homogeneous nucleation, particles formed via miniemulsion however are mainly formed by droplet nucleation.
18.
By seeding with aerosols, ice crystals could grow rapidly and deplete water vapor, suppress nucleation and any growth of ice crystals by homogeneous nucleation.
19.
Since homogeneous nucleation forms dislocations from perfect crystals and requires the simultaneous breaking of many bonds, the energy required for homogeneous nucleation is high.
